TECHNICAL SPECIFICATION: JiRack 236B Frontier Cluster
Document ID: CMS-JR-236B-PROC-2025
Project: JiRack Balanced Frontier Deployment
Lead Architect: Konstantin Vladimirovich Grabko
1. COMPUTE SYSTEM (High-Density GPU Nodes)
The deployment requires a minimum of two (2) fully populated 8-GPU nodes to achieve the necessary VRAM and throughput for the 108-layer dense architecture.
| Component | Minimum Specification | Required Feature for JiRack |
|---|---|---|
| Chassis | 6U - 8U Rackmount (e.g., NVIDIA HGX H100) | Support for 700W SXM5 GPUs |
| Accelerator | 16x NVIDIA H100 80GB (SXM5) | 1.28 TB aggregate HBM3 VRAM |
| GPU Interconnect | NVLink + NVSwitch (900GB/s) | High-width Tensor Parallelism (TP) |
| Processor (CPU) | 2x Intel Xeon Platinum 8480+ (per node) | 224 total cores for BRE routing |
| System Memory | 2TB DDR5-4800MHz ECC | Weight-caching for 108 layers |
| Local Storage | 8x 3.84TB NVMe U.2 (RAID 0) | Sequential read for fast model loading |
2. NETWORKING & FABRIC (Low-Latency Backplane)
Because the 236B model requires frequent cross-node communication (Pipeline Parallelism), standard Ethernet is unacceptable.
- Primary Fabric: NVIDIA Quantum-2 InfiniBand (NDR 400Gb/s).
- Adapters: 8x ConnectX-7 NDR InfiniBand cards per node (1:1 GPU-to-NIC ratio).
- Switching: 1x QM9700 Quantum-2 Switch (64 ports of NDR).
- Features: Must support GPUDirect RDMA and SHARPv3 (Scalable Hierarchical Aggregation and Reduction Protocol) to offload 14:1 GQA reduction tasks.
3. POWER & THERMAL MANAGEMENT
Operating a 236B Frontier model at 100% duty cycle generates extreme thermal load.
| Parameter | Specification |
|---|---|
| Peak Power Draw | 10.2 kW per server (~22kW total including switching) |
| Voltage | 200V - 240V AC (3-Phase Delta/Wye) |
| Cooling Type | Rear Door Heat Exchanger (RDHx) or Liquid Cooling (D2C) |
| Ambient Ops | 18°C – 24°C (64°F – 75°F) with N+1 Redundancy |
| Rack Rating | 48U Heavy-Duty (Static Load: 1500kg+) |
4. SOFTWARE STACK & COMPLIANCE
- OS: Ubuntu 22.04 LTS (NVIDIA-Certified).
- Driver: NVIDIA Data Center Driver (Current 5xx.x branch).
- Middleware: CUDA 12.x, NCCL 2.x, and cuDNN.
- Security: TPM 2.0 and Secure Boot (Mandatory for BRE architecture protection).
5. LICENSING & ATTRIBUTION (MANDATORY)
